I have some questions about IBS. It all started last week when we went out for dinner and I had to go to the bathroom, but decided to hold it until we got home. Once we got home, I barely made it to the bathroom. Eversince that episode, I have period pains on my right side below my ribs and sometimes when I go to the bathroom... both ways. Does this sound like IBS?? The pain feels like a pulled or strained muscle. PLEASE HELP!!!
